The code below is to demonstrate color afterimages. The user chooses a color, fixates the changing numbers at the center until they reach 30 (seconds), then manually switches to white to observer the ...

I am trying to manipulate my contour plots altogether in one Manipulation. I have 8 different contour plots and when I put them in "show" they combine. But now I want them to "manipulate". How do I go ...

I would like to solve equation for the 2D distribution of an electrical potential in the conductive medium:
$$\nabla\cdot(\sigma\nabla f) = 0$$
where $f=f(x,y)$ is the electric potential (in 2D) and ...

Does anyone have an example of a Manipulate demonstration where the user can type into a box the differential equation, time interval, initial condition, and the result is plotted?
This possible in ...

I have a dataset that has a number of groups with overlapping sets. There is a point in the group within the intersection of the sets that I want to highlight by placing a marker of that point between ...

My application relies on the ability of users to enter text, and has several settings with a huge range of potential values best entered as strings (to comply with Wolfram's admonition to "choose your ...

I am trying to make a demonstration that can take in a matrix and create a vector field. Currently I have the demonstration all functioning but to define the matrix it uses sliders. I know they cannot ...

I have a grid of values generated from a MATLAB evaluation. Most of these elements are 0, some 0.5 and the remainder 1. I'd like to write a mathematica script which reads in the CSV and then, in every ...

I have a problem with showing my results correctly in a Manipulate in a cdf-file.
My program (for my bachelor thesis) can calculate the income law with a income entered into an input field; the use ...

I'm developing a demonstration that allows students to explore the location of a point on a number line simultaneously at various scales. I'll show a very simplified version here to get to the nub of ...

I'm trying to display some graphs, which were defined with plot above this line of code. The parametric plot moves through all of the x values, the others are stationary. I would like the parametric ...

With help from some of you guys here in this forum, I have developed the following code, which works perfectly. My questions are:
how to automate the simulations with varying initial conditions. In ...

My function "DefineRss[]" takes in three arguments and outputs a plane value.
It sits in the first argument of the function plot3D and that in turn sits in the manipulate function
The function also ...
